The hexa- and pentapeptide extension of proalbumin. II. Processing of specific antibodies against the synthetic hexapeptide.
The chemically synthesized proalbumin hexapeptide was coupled to rabbit albumin with carbodiimide. Subsequently rabbits were immunized by subcutaneous injection of the conjugate. After 5 weeks the rabbits had developed antibodies against the hexapeptide, which could be detected by immunodiffusion. A sensitive enzyme-linked immunosorbent assay was developed. Using the hexapeptide and other very similar peptides as antigens, a high specificity of the antibodies against the proalbumin hexapeptide was found.
